`TOOL FOR FlNlSHING BOTTLE-HEADS.

SPECIFICATION forming part of Letters Patent 361,774, dated April 26, 1887.

(No model.)

to provide a tool which will provide annular grooves and offsets of any desired shape in the inside of the bottlehead and annular offsets of any desired shape on the outside.

The invention consists in the combination, with a mandrel, of dies mounted in a slot in said mandrel and adapted to be pressed from each other and to be projected from the sides of the mandrel, which dies are operated by springs held between Springarms on which the jaws or formers for shaping the outside of the bottle-heads are provided, all as will be fully described and set forth hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of my improved tool for finishing bottle-heads, the bottle-head being in section and the tool being open. Fig. 2 is a longitudinal sectional View of the same, the tool being closed. Fig. 3 is a sectional view of the tool and bottle-head on line x x, Fig. 2. Fig. 4 is a sectional plan View of the tool on the line y y, Fig. 2. Figs. 5, 6, 7, and S are crosssectional views of different bottle-heads formed by means of my improved tool. Fig. 9 is a cross-sectional view of the mandrel.

Similar letters of reference indicate corresponding parts.

The two arms A A are made integral with the cross-piece A', all of steel, tempered to have such tension as to press the free ends of the arms from each other. On the ends of the arms A A the jaws, pressers, or formers B are formed, the inner surfaces of which are shaped the same as the desired contour of the outside of the bottle-head, so that when the jaws are pressed as close together as possible the crosssection of the space between the jaws or formers B will be the same as the cross-section of the bottle-head.

The mandrel C is formed on and projects from a plate, E, between the jaws B, that face ofthe plate from which the mandrel projects being at right angles to the longitudinal aXis of the mandrel. The width of the plate E is such that when the inner sides of the jaws B rest against the side edges of the plate E the jaws will be separated a distance equal to the diameter of the bottle-head-that is to say, the jaws can only be pressed together until they rest against the side edges of the top plate, E, and when thus pressed together as far as possible they are in proper position for shaping the outside of the bottle-head. The mandrel is provided in two opposite sides with two liattened portions, C', as shown in section in Fig.

9, near the free end of the mandrel, so as to permit the escape of the air through the neck of the bottle when the mandrel is being intro duced.

The plate E is formed on the end of a stem, F, which is widened from the plate E to a point below the middle of its length, and has a slot, G, formed in the widened part. The

end of the stem F is screw-threaded and is lpassed through an aperture in the cross-piece A, uniting the shanks A. ,A nut, F, is screwed on the threaded end ofthe stem before the same is passed through the aperture, and on the threaded stem, below the crosspieee A', are screwed the nuts F2 F3. When the nuts F2 F3 are removed, the nut F' is turned or adjnsted until the top surface cf the plate E is inthe proper position in relation tothe inside of the jaws or formers B, and then the stem is locked in place by means ofthe nuts F2 F3 or other similar devices.

In the lower end ofthe slot G of the widened part of the stem F two spring-levers, H, are fastened, which are pressed toward each other by their spring-tension, the upper ends of said levers passing through and into a slot, J, formed in the top plate, E, which slot is in communication with the longitudinal slot K formed in the mandrel in those sides facing the inner surface of the jaws or formers B. The

outer sides of the spring-levers H within the slot J are notched, recessed, or otherwise ducing the grooves, notches, recesses, or offsets in the inside of the bottle-head. The dies may be of different shape, according to the desired shapes of-the grooves or recesses in the inside of the bottle-head.

Two pins, M, are held by nuts, one in each shank or arm A, which pins M pass through that side of the slotted stem F nearest the shank or arm A in which said pin is held, and also passes through slots in the two spring-levers H, and into a slot in the other sideof the slotted part of the stem F. A cross-pin, N, is passed through the free end of each pin M, and each pin is provided with an offset or shoulder, O, resting against the inner surface of that springlever H adjacent to the arm or shank A opposite the one in which said pin M is heldthat is to say, the pins'M cannot act on that spring-lever H adjacent to the shank or arm in which said pin M is' held, but act on the other spring-lever H.v It is evident that the apertures for one and the same pin in the two spring-levers H are of different sizes, as shown. p

The parts A`l of the shanks or arms A are rounded on the outside, as they are to be used as handles, and are preferably covered with asbestus and with chamois or buckskin, so as ing-rings, rubber or other Stoppers, 8vo.

In case the outside only of the head is to be formed with an offset, &c., a smooth mandrel is used and the dies L dispensed with, and the inner surfaces of the jaws or formers B are shaped accordingly.

Fig. 8 shows a bottle-head in which a collar is formed on the outside of the head and the inside is smooth.

' The operation is as follows: Ordinarily the spring-tension in the shanks or arms A and their cross-piece A keeps the jaws separated, as shown in Fig. 1, and the dies L are within the slots J of the mandrel-that is, they do not project from the outer surface of the mandrel. The bottle-head can be placed on the mandrel or removed very easily, as the outside of the mandrel is smooth. To finish a bottle-head,

the mandrel C isintroduced into the head when the same is in a red heat and soft, and the jaws A A are pressed toward each other until they rest against the side edges of the plate E, whereby the adjacent or inner surfaces oi' the jaws or formers B are pressed against the outside of the bottlehead. By pressing the Shanks or arms A toward each other the spring-levers H are moved from each other as the shoulders O of the pins M act on the inner sides of the said spring-levers H. The dies L are thus forced out of the recesses J in the lower part of the mandrel and into the soft glass on the inside of the bottle-head. The bottle is held securely by the jaws B, and is then passed over a board or table, so as to be rotated on the mandrel C, whereby the desired annular grooves are cut on the inside of the bottle-,head by the dies L. The jaws A are then released and spring from each other,

thereby drawing the spring-levers H together, whereby the dies L are Withdrawn from the grooves which they have formed in the bottlc-head, thus permitting of withdrawing the .mandrel from said head.

The bottle-heads are all shaped alike, for the reason that the dies L are in all cases `pressed the same distance from each other and the same distance out of the mandrel. The jaws B cannot be pressed together any closer than until they rest against the side edges of the plate E, and themandrel cannot be forced into the bottle-head'any farther than until the end of the head rests on the plate E, which plate E finishes off the edge of the bottle-head true and square.

In' case it is desiredto form a different groove in the bottles,.the stem F is removed, and the spring-levers H are replaced by others, in which the proper dies are held.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. In a tool for iinishing bottle-heads, the combination, with spring-arms having jaws or formers formed on their ends, of a fixed plate between the jaws and independent of the same, against which plate the jaws can be p ressed, a mandrel projecting from said plate, and dies held in the mandrel and mounted to be projected from the sides of the mandrel, substantially as shown and described.

' 2. In a tool for finishing bottle-heads, the combination, with spring-arms having jaws or formers on their ends for shaping the outside ofthe bottle-head, of a slotted stem, F, the plate E on said stem, a mandrel projecting Afrom the plate, spring-levers held in the slot of thestem, dies formed on the ends of said spring-levers within a slot of the mandre1,an.d pins connecting the spring-levers with the springarms on which the formers or jaws are provided, substantially as shown and described.

3. In a tool for finishing bottle-heads, the combination, with spring-arms having jaws'or formers on their ends, of the slotted stem F, the plate E on the same, a mandrel projecting from the plate, spring-levers in the slot of the said stem, dies formed on the ends of the springlevers, and nuts foradjusting and locking in place the stem, substantially as shown and described.

4. In a tool for iinishing bottle-heads, the combination, with the spring-arms having jaws on their ends, of a fixed mandrel between the jaws, said mandrel being flattened at opposite sides, and movable dies held in the slot in the mandrel, which dies are operated from the spring-arms, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
